High Idle – Driver Adjustable
Details & Technology
This electronic RPM governor maintains a constant RPM, e.g. for auxiliary drive operation.
Under load change, RPM may fluctuate by approx. +/- 50 RPM (depending on engine, load
and RPM).
The high idle factory setting is 950 RPM. The factory setting can be adjusted by the dealer
using the Star Diagnostic System to a different value.
The RPM setting can be driver adjusted in 50 RPM increments up or down by using the
rocker switch.
Benefits & Arguments
Constant engine speed, variable settings
Necessary if a virtually constant rpm must be maintained in order to operate an auxiliary unit
such as a loading crane.
Remarks
Not suitable for operating 220V generators!
If necessary, can also be programmed to allow the cruise control stalk to be used for
changing the RPM setting.
Recommended for:
- Ambulances
- Shuttle services
- Applications with longer idle times
